To get the engine cranked and running, here is what I would do. If the engine is not stuck ,I would first remove all of the spark plugs. I would turn the engine over with the starter while holding my thumb tightly over the spark plug holes. While turning the engine over it should blow your thumb off the plug hole when it comes up on compression. If all cylinders pass the thumb test, You have compression. Any cylinder that fails the test will probably have a stuck valve in the open position. If the engine only turns a small amount and then will turn no farther, a valve is probably stuck in the closed position. A tight or rebuilt engine is more likely to stick than a worn engine. If it turns and passes the thumb compression test, I would change the oil. First remove the distributor, drain the oil, pour three quarts in the oil filler tube and one quart in the hole that the distributor came out of. Replace the distributor. I would then Throughly sand the contacts on the points and set the gap at .022, clean the rotor tip with fine sandpaper, clean and set the gap on the spark plugs at .035. I always polish up the spark plug connectors with a scotch brite pad or steel wool. You will need to drain the old fuel and replace with fresh gas without ethanol if you can find any. If gas starts pouring out the carburetor when the gas is turned on, first try tapping on the top of the carburetor with a wrench or screwdriver handle to jarr the needle valve, unstuck. If tapping on top of the carb doesn't stop the leak, it will be necessary to remove and clean out the carb. If all of the tests passed I would push the spark lever all the way up, turn the knob on the choke open about one turn to the left off the seat, pull the throttle lever down verv slightly, Turn the ignition on , pull the choke and press the starter button. If it was running when it was parked this should get you started. It won't take much choking, usually one turn of the engine with the choke pulled is all that is needed, You don't to flood the engine. If it cranks pull the spark down and adjust the throttle lever for idle. when it warms up a bit and begins to lope, close the knob on the choke to the right until it is about a quarter turn off the seat. This should get you going. Good luck.
